Problems solved by technology

[0003] However, when the blower is used in the cement production industry, there is almost no back pressure in the combustion kiln when the ignition is started, and, in order to prevent the flame from being blown out due to excessive air volume, the air volume required by the combustion kiln is small, and the blower is required for 1-3 Hours of low-speed operation, and the vent valve matched with the blower cannot reach the closing pressure of the vent valve when the blower is running at low speed. Specifically, due to the friction of the vent valve connecting rod movement, product processing errors, etc. When the gas pressure is less than 10 kPa, the vent valve cannot fully move due to its inability to overcome its own friction and the pressure of the pipeline, resulting in the venting and opening of the blower for a long time, which in turn makes the blower unable to effectively transport the air to the process point , and continuous shorting will produce huge noise

Embodiment 1

[0044] This embodiment provides a vent valve assembly, which is applied to the blower system and is used in conjunction with the blower 10. When the blower 10 is running at a low speed, the vent valve 1 can be in a closed state, preventing the blower 10 from being vented and opened for a long time, thereby making the blower 10 It can effectively transport the air to the process point, and at the same time, it can reduce the generation of noise. It should be noted that the blower system can be applied to the cement production industry, that is, the blower system sends air into the combustion kiln 100 .

[0045] See figure 1, The vent valve assembly includes a vent valve 1, a three-position three-way solenoid valve 2 and a controller (not shown).

[0046] Wherein, the vent valve 1 may be a vent valve 1 in the prior art, specifically, the vent valve 1 has a first port and a second port. Gas can enter the vent valve 1 through the first port, and flow out of the vent valve 1 thro...

Embodiment 2

[0056] This embodiment also provides a blower system, which can be used to charge air into the combustion kiln 100 . Such as Figure 1 to Figure 4 As shown, the blower system includes a blower 10 , an exhaust main pipe 20 and the vent valve assembly described in the first embodiment.

[0057] The blower 10 is a structure in the prior art, and its specific structure and working principle will not be repeated in this embodiment. In some embodiments, the blower 10 and the three-position three-way solenoid valve 2 share a controller. Specifically, the controller is connected to the blower 10 to control the state of the blower 10, such as starting, closing and rotating frequency of the control blower 10. Specifically, the controller controls the frequency of the frequency converter in the blower 10 to control the blower 10. Rotating speed. In other embodiments, the blower 10 has its own control system, and the frequency of the frequency converter is controlled by the control sys...

Embodiment 3

[0062] This embodiment provides a blower system control method, which is used to control the blower system described in Embodiment 2. The control method of the blower system includes an ignition step, such as Figure 5 As shown, the ignition steps include:

[0063] S1. Close the main valve 50 of the blower system, and open the branch valve 60 of the blower system.

[0064] After the main pipe valve 50 is closed and the blower 10 is started, the gas in the exhaust main pipe 20 cannot pass into the combustion kiln 100 and can only be discharged through the second branch pipe 30 .

[0065] S2. The three-position three-way solenoid valve 2 controlling the vent valve assembly is switched to the third position, so that the first branch pipe 4 communicates with the second interface.

[0066] After step S1 is executed, the user can manually input an ignition mode preparation command to the controller through the touch screen of the blower system, and after the controller receives the...

Abstract

The invention discloses a vent valve assembly, a blower system and a control method thereof, which belong to the technical field of blowers. The vent valve assembly includes a vent valve, a three-position three-way solenoid valve and a controller. The vent valve has a first interface and a second interface , the first interface is connected to the exhaust main pipe of the blower system; the three-position three-way solenoid valve has a first station, a second station and a third station, the second port is connected to the three-position three-way solenoid valve, and the three-position The three-way solenoid valve is also connected with a pressure relief pipe and the first branch pipe. The first branch pipe is connected to the blower or exhaust main pipe of the blower system; the controller is connected to the three-position three-way solenoid valve, and the controller is used to control the three-position three-way The solenoid valve is switched to the first station, the second station or the third station. The invention can prevent the blower from being emptied and opened for a long time when the blower is running at a low speed, so that the blower can effectively transport the air to the process point, and can also reduce the generation of noise.

Description

technical field [0001] The invention relates to the technical field of blowers, in particular to a vent valve assembly, a blower system and a control method thereof. Background technique [0002] The vent valve is one of the accessories that the blower must be equipped with. The vent valve is used to relieve the pressure of the outlet pipe of the blower before the blower runs to the rated speed, so as to avoid the blower starting under pressure, thereby preventing the occurrence of surge, and venting The valve is also used to release the pressure of the outlet pipe of the blower when the blower is stopped, so as to avoid surge when the blower stops. It can be seen that the vent valve can protect the blower. [0003] However, when the blower is used in the cement production industry, there is almost no back pressure in the combustion kiln when the ignition is started, and, in order to prevent the flame from being blown out due to excessive air volume, the air volume required ...
